Description

"Paste-like peracids"

The present invention relates to pastes containing active oxygen, their use and packaging, and a method for producing corresponding pastes.

Liquid to pasty detergents have become known in large numbers in particular recently. They are usually tailored to the needs of the household, so that they usually have to be sufficiently liquid to be poured and dosed without problems. Such liquid detergents should also be stable in storage within relatively wide temperature ranges.

EP 721 498 describes how, by changing the viscosity and the thixotropy, paste-like compositions are obtained which have such a high viscosity at room temperature (20 ° C. to 25 ° C.) without the action of shear forces that they neither flow out of nor through a container easy suction can be promoted. The shear effect of a movable plate or even a pressure stamp, as provided in the metering system according to German Offenlegungsschrift DE 37 19 906 A1, is generally not sufficient to reduce the viscosity of the pasty agents to such an extent that they are conveyed by a suction pump can be. Only higher shear forces, as can be achieved, for example, with the metering device according to patent application EP 721 521 "paste container with removal device", are able to do this, the paste-like means not separating during shearing and after the shearing process has ended, for example if not the entire contents of the storage container are to be dosed into the washing machine at once, again largely having the same properties as before the start of the action of shear forces.

It is also known in the prior art that compounds containing active oxygen, such as peracetic acid or hydrogen peroxide, are used for disinfection. can use. Most of these compounds have a broad spectrum of antimicrobial activity.

Patent EP 765 309 relates, for example, to storage-stable aqueous ester persic acid solutions and their use as disinfectants.

In German Offenlegungsschriften 26 55 599 and 28 15 400 it was proposed to produce organic peracids for disinfection shortly before use from more stable precursors, namely from sodium perborate and acid anhydrides.

According to German Offenlegungsschrift 27 01 133, aqueous peracid preparations are obtained from hydrogen peroxide releasers and aromatic acyloxycarboxylic acids. The storage of ready-made peroxide-containing formulations is limited depending on the ingredients.

EP 357 238 comprises antimicrobial compositions which, in addition to a strong oxidizing agent! selected from peracetic acid and lithium hypochlorite, copper and brass corrosion inhibitors, a buffer substance, an anticorrosive agent that inhibits corrosion of various metals and contains a wetting agent.

EP 799 297 B1 discloses thickened aqueous compositions which contain a soluble peracid in solution together with a thickener. It appears from the application, page 6, lines 14 to 16, that thickened compositions are understood to mean recipes which, due to a suitable choice of the thickener system and the surfactants, have viscosities of 100 to 500 cPs. A cPs is known to correspond to one milli-pascal second. Such viscosities, as can be found in the electronic edition of the Römpp Lexicon, Chemistry Version 2.0 under the keyword 'viscosity', are in the range of motor oil. The object of the present invention was to develop pasty agents containing active oxygen. These should have a higher viscosity than the active oxygen-containing agents known in the prior art, the viscosity possibly being reduced under the action of shear forces.

The object was achieved by providing pastes containing active oxygen which a) hydrogen peroxide and / or one or more water-soluble percarboxylic acids or their anions and b) one or more viscosity-increasing components, such as polyvinylpyrrolidone, fatty acid, amine oxide, phosphonic acid esters, Fatty alcohols or phthalamidopercarboxylic acid (PAP) in the event that a) is not phthalamidopercarboxylic acid, and

Contained water and optionally other auxiliaries and active ingredients.

Preferably, the active oxygen-containing pastes without the action of shear forces have a viscosity such that they are not flowable at room temperature under the action of gravity, but have a significantly lower viscosity when sheared and are flowable under the action of gravity. This property can be checked experimentally by measuring the paste viscosity under different shear conditions. One way of doing this is to use a conventional rotary viscometer at different speeds of rotation of the spindle. Pastes according to the invention preferably have a viscosity of 10,000 to 200,000 mPa.s, in particular 20,000, at 25 ° C. using a Brookfield (^) rotary viscometer DV-II or DV-II plus with spindle No. 7 at 5 revolutions per minute mPa-s to 100,000 mPa-s, and at 50 revolutions per minute a viscosity between 1000 and 60,000 mPa-s, in particular from 3000 mPa s to 30,000 mPa-s.

In many cases, hydrogen peroxide is a preferred component of the paste, especially when it is present in addition to organic peracids. When it comes to providing particularly preferred low-odor pastes without using unpleasant-smelling percarboxylic acids, combinations of hydrogen peroxide with PAP and / or succinic acid esters are preferred for use. Such formulations have the advantage that they give stable pastes and also have a very good disinfecting effect within a wide temperature range.

The pastes according to the invention preferably contain, based on the total paste, 0.01 to 90% by weight, particularly preferably 0.1 to 60% by weight, of the components listed under a).

It is further preferred that the components listed under b) make up a total of between 0.01 and 30% by weight, based on the total paste, with it being particularly preferred if between 0.1 and 20% by weight .-% of the components listed under b) are present.

In a further preferred embodiment of the present invention, the components listed under a) are selected from hydrogen peroxide and / or the group having the general formula I.

the group of phthalamido-percarboxylic acids (PAP) or their anions, the percarboxylic acid component containing 1 to 18 carbon atoms.

It is further preferred that the paste according to the invention as components a) based on the total paste

EP 597 877 discloses mixtures which are also combinations of short-chain with long-chain peracids. However, it was not recognized in the abovementioned application that the production of pastes is positively influenced by such combinations. On the contrary, EP 597877 even recommends adding hydrotropes on page 3, lines 56 to 58, in the presence of higher molecular weight fatty acids, in order to solubilize the concentrate.

It is to the merit of the present invention that it was recognized that stable peracid formulations can also be formulated with very long-chain fatty acids or perfatty acids without the need to use additional hydrotropic compounds. In the paste, the weight ratio of the components listed under i) to the percarboxylic acids listed under ii) or their anions is preferably 15: 1 to 1: 3.

Furthermore, it is preferred that in the inventive paste component a) is selected tansäure from hydrogen peroxide, peracetic acid, perpropionic acid, Peroc-, phthalimidoperhexanoic acid, Phthalimidoperoctansäure, persuccinic acid, Persuccinsäuremonomethylester, perglutaric acid, methyl ester Perglutarsäuremonome-, peradipic, Peradipinsäuremonomethylester, persuccinic, Perbernsteinsäuremonomethylester or anions thereof ,

It is particularly preferred if hydrogen peroxide is present as component a) and phthalamidopercarboxylic acid as component b) in the paste according to the invention.

This combination has the advantage over many other conceivable combinations that it has practically no unpleasant smell and also has very good antimicrobial activity and bleaching action both at low temperatures of around 10 to 40 ° C. and at temperatures above it.

In a further preferred embodiment of the present invention, the paste according to the invention contains, in addition to components a) and b), one or more nonionic surfactants of the general formula (III),
